Re: Latitude and Longitude by "Noon Sun"

     Instructions for my plastic sextant use a 'noon sight'
    example for obtaining a fix. Obtaining both longitude
    and latitude by one simple process is alluring to me.

    There are purists who scoff at imperfection and those, like
    myself, who are not into nuance but are just trying to comprehend
    basics. When I navigate accurately enough to sight a landmark
    for my final approach, it's a success.

    May I suggest a noon sight fix might suffice for verification
    of the dead reckoning position required for a direction/intercept
    fix? Might that fix actually be superior to a DR position that
    hasn't been updated during a period of prolonged cloud cover?
